Re: [Veritas-bu] Quick Erase Script (Windows)

Daniel, I use the follow script (nothing to do with scratch tapes) when space gets tight on our DDs and I want to pre-expire some NBU images.

----------------------------

#!/bin/sh

for tapeid in `cat delete-DD.txt`; do
    slot=`vmquery -m $tapeid | grep "robot slot"`
    slotn=`echo $slot | cut -b 13-`
    barcode=`echo $tapeid"L1"`
date
echo $barcode
echo $slotn
# Netbackup Expire the tape.
      bpexpdate -m $tapeid -d 0 -force
      vmdelete -m $tapeid -h b2u32
#
# DD - Export/Delete/Add/Import the tape
ssh -l sysadmin datadomain "vtl export DD-VTL slot $slotn"
ssh -l sysadmin datadomain "vtl tape del $barcode"
ssh -l sysadmin datadomain "vtl tape add $barcode capacity 100"
ssh -l sysadmin datadomain "vtl import DD-VTL barcode $barcode"
done
ssh -l sysadmin datadomain "filesys clean start"
-----------------------------

The L1 above is because we use LTO1 in the DD.

SSH keys are setup from one of our Linux Media Servers to do both the NBU and DD commands.

Try running quick erases on your tapes after you run a filesys clean and then run a filesys clean again and see if you recover additional space on the DDR’s. This will tell you how efficiently you are using your tapes. In addition, this is information we received from our Data Domain representative and from other techs we have worked with so this takes us right back to why we need the script.

We use Data Domain here and haven’t seen that.

Are you running image cleanup jobs in NBU?

When you use Data Domain DDR’s if one of the tapes becomes scratch and is not re-used right away, they hold data that is not cleaned up on the DDR until they are used or quick erased so there can be a few GB’s or several hundred GB’s that can be sitting on the DDR that can be cleaned up. Which is why we are looking for a script.

There’s no need to erase scratch tapes. When they are scratch then they will be overwritten the next time NBU uses them.

Hey guys

Does anyone have a quick erase script for Netbackup 6.5.3.1 (Windows 2003 Enterprise server)? I would like to be able to schedule the script to find all scratch tapes and run a quick erase on these tapes on a weekly basis. In addition, we have Unix utilities on the box so we can use these commands on the server. Any assistance would be appreciated, thanks.
